I am just quoting what Crawford was stating that the FA20 yields more HP than an EJ on the same turbo. Because of this I am concluding that a NA FA20 will yield more HP than an NA EJ. Granted percentage increase in HP will be different but FA20 will yield more HP nonetheless. Also I would like to add that Subaru used the FA20 engine because a NA EJ20 or EJ25 can not reach the desired goal of 200 crank hp on pump. May be if you modify the design of the EJ20/25; Longer stroke, higher compression piston, DI/PI fuel deliver and redesign the rods to achieve a higher reving motor.
But wait, Subaru did modify the EJ20/25 motor. It's called the normally aspirated high reving FA20 motor.
